Recommended cable for a 100' run on SDS 100

[Jondrew55]

Many, many years ago I obtained an EE degree so I understand signal loss, dBs, connector losses etc at a basic level. But I also know running the calculations is not the whole answer. Product quality is another factor.

I have an SDS 100 and bought a Diamond D3000N discone antenna which is now sitting in my upstairs bonus room. It has definitely improved the reach of my scanner, but putting it up on my roof would most likely improve it further. But there's that HOA thing I have to deal with. However, if I put the antenna just at the roofline at the rear of my house, I may be able to sneak it in under the "out of sight" escape clause. But in order to do that, I'm estimating I'll need about a 100' run of cable. I listen to pretty much the full band on the SDS 100, so I want the minimal loss for all of them. I've seen the cable loss calculators so I have an idea what I'm up against. There seems little point in going thru this exercise if I end up with the same basic reception from the roof I'm already getting from my 2nd floor interior room.
I'm looking for recommendations for high quality cable. I can solder, so I can put my own connectors on, but I'd be fine buying something with the N connectors already attached. I see this cable on Amazon for $95. Can someone recommend something better? Or am I just chasing a unicorn here?

Do not buy AMAZON CHEAP CLONE 9913.
Go to a Radio Shop and buy true Belden 9913.
Before you spend about $2.00 a foot for quality cable what are your listening habits VHF 150, UHF 460, Trunking 700/800 and how far away are the sites you want to monitor?

Don't use that fake POS junk coaxial cable from Pandaland that is sold from a warehouse outlet that does not specialize in two-way radio electronics. Get quality stuff from a reputable two-way radio retailer and do it once and save time and money in the long run.

The SDS 100 is a portable receiver. Take it outside and go up a ladder to where on the (edge?) of the roof you're planning to put the antenna. Compare the signals coming in to what you are now getting with the discone indoors on the 2nd floor. Listen for awhile and note the signal strengths of your "usuals" for monitoring. Are they better overall? If so then loss in a good cable may not be that impactful to the sigs you'll see at the SDS 100. Are they the same or worse? Then you may want to leave the discone right where it is now.

Amazon shows the seller as XRDS-RF, but who are they? Is there a real company behind XRDS-RF? Or, are they just a reseller of inexpensive, low-quality products?

I got my Times Microwave LMR 400 from Antenna farm. You can get any length your want with whatever connectors you want. Note, that you're going to need something smaller coming inside and hooking up the the SDS100. Pretty sure I used LMR 200.

Yes, those are the frequency ranges I'm listing to. How far am I from the sites? The low freq sites, which are the ones I'm having the most trouble hearing are anywhere from 3-8 miles away. Trunking sites seem to come in from quite a distance, as I assume I'm picking them up thru some sort of repeater (I'm new to this, so I'm learning. I only put that amazon link in there because I was was just looking for a starting point.
